The purpose being to iluminate a north side wall of a house to decrease mold growth. - One single large convex mirror, or an array of many small convex mirrors (equal in mirror area) - Which choice will reflect more sunlight to the dark wall for a decent number of sunlight hours and angles daily ? Or is there a preferred shape as ellipsoidal for the task ?

How simple or complex is it ? What amount of deeeep knowledge is needed to do such ? Or is just to read a instructional and do it as explained there ? Just an example : vinpocetine or ethyl apovincaminate; reportedly extracted from a plant vinca minor, which shows bearing a dozen chemicals; is each one an entire world of knowledge in how to extract, what proven applications has... But... comes from bark, root, fruit, flower... Where is it found in written ? Is there a 'CRC' type of fat book for such knowledge ? Or are these industrial/pharmaceutical top secrets ? How to find how is it done; if it is extremely difficult, critical, or a piece of cake; it there a standard published process guide for the example and for thousand of other processes alike ? Correct, I know peanuts about biochemistry.

Not a book, but on screen... triggers imagination on how would life was then. A bit here and there on ancient legislation : http://avalon.law.yale.edu/medieval/laws_of_thekings.asp from : http://avalon.law.yale.edu/subject_menus/ancient.asp "If any one bring an accusation against a man, and the accused go to the river and leap into the river, if he sink in the river his accuser shall take possession of his house. But if the river prove that the accused is not guilty, and he escape unhurt, then he who had brought the accusation shall be put to death, while he who leaped into the river shall take possession of the house that had belonged to his accuser." (The Code of Hammurabi)

When it 'first' hit the fan, it was 1941. But the fan and the room and the entire matter that hit the fan was contained within that room. http://www.seekingmoinfo.com/LeonardHStringfield.html After analysis of that 'first' recovery, this document was written : http://www.bibliotecapleyades.net/archivos_pdf/oppenheimer_einstein.pdf ------------------------------------------------------------------------------------------------------------------------------ Not videos, but here is dozens of simple documents like this : http://roswellproof.homestead.com/files/ROSDEBRI.DOC And much better ones too. So abundant in hundreds of web sites, that interest is lost in following or reading them start to end.

Yep. Dietary rules mandated by God to prevent diseases created by God. If the diseases were created by demons, who created demons... God -creator of everything-

Thanks. OK, good explanation there; for maintaining good health. Acceptable. Do not know why eating unlisted kangaroo, iguana, penguin, vicuña, orca... would or would not be healthy. "It was thought" by who ? By the decretor of the dietary rules ? And that was... And the purpose of avoiding contracting dangerous diseases... those diseases were created by...

I meant if the message came from God, who knew all species himself created in all other continents, why weren't those listed, as the turkey among many...

Any reason on the selection of what to eat and what not to ? Are the animals listed only local fauna on the middle east, not including other 'creations of God' from other continents ? Guinea pigs, crabs, lobster, turkey, clams... are they "unclean" ?

Not graphite; not graphene; not new either : ---->http://www.bareconductive.com/

Thanks. The coolant these people market is about 68% ethylene glycol + 30% propylene glycol + corrosion inhibitors Polyethylene glycol is not in the picture.

What are the hurdles that prevent from coming up with at least a working gadget beyond keeping it just as a curiosity for scratching heads ? How would you design a useful machine from this 'borrowed' technology nitinol (Nickel Titanium Naval Ordnance Laboratory) ? Is there a way to formulate the alloy for smaller delta temperatures ? Please ignore the "Free" word in the title below. Does not apply. ----> You will read between the lines it is a 'Godsent' material... Yeah, call it 'God'

Did a quick preliminary qualitative test; based in gas production, about a spoonfull of acetone in a -say non-latex bladder- with a 5 watt immersed bulb in it as heater element. Initially there is no gas in it, just the liquid acetone. Power would come from a battery/solar cells on the glider wings. After a few minutes, bubling was very active. One hour later, gas was about six times the amount of liquid acetone. Too long for a preferred 'snapping' action of immediate surfacing. Yes, it would surface anyway as there is some buoyancy provided, but too late? The bouyancy, small and took too long to produce with five wattshour, could be increased with more power, BUT that test was at atmospheric pressure (not at ocean depths pressure onto the bladder, and at room temperature, not at cold depth temperatures) which both together would greatly impair the gas expansion amount. To follow some day, based in a micro compressor. Sucking gas from a bladder to a lesser volume vessel to promote sinking. Instantaneously releasing it back to the bladder to start surfacing. Will see... -Not ready yet for complex materials quicky tests-

Resurrecting the topic; just found someone is doing what I was after, and been after, for maaaany years.

Opinions ?

Thanks, Marc, for your very elaborated and time consuming posts #21 and #22 above. Clearly show your involvement in the subject, your knowledge and expertise. The exposure of alternatives where you poured your brains onto it. Once I learned that simple projects do not yield huge successes; complex problems do. Complex tasks requiere of these complex engineering considerations. Currently in the pursuit of parts to build a few alternates to test and evaluate, hampered by imminent moving to another state and holding back progress and working with more dedication to the glider model. But will be back with more adrenaline when settled.

No matter how good the chemical conductor be and easy to trace as with a pencil; circuits the way you envision are just the paths between components. Components are not meant to be just touching the graphite or other traces, but to bond intimately to them, and as they use metallic leads; securing a reliable connection would be a nightmare. Forget it ! In early nineties, I serviced an experimental? PCJr. ? by IBM that had its plastic cabinet internal surfaces painted/sputtered with copper and that paint etched with the components soldered onto it. So there was no fiberglass board; the PC cabinet was the board. Seems it did not provide much for the future as never saw that method used again.

Sorry, another brain fart from poor English : shoud say bearing ball , or steel ball above instead of ball bearing.

Thanks, gentlemen. I came up with an hysteretic mechanism, but appreciate your inputs. ----> A plastic pipe with a ball bearing inside and weak magnet end caps.

..."Whelks, in my opinion have very little taste and lots of texture. Not good eating.".... Didn't anyone tell you to eat only what is inside of the shell ?

Thanks Marc for your elaborated and thoughtful post using purely delta temperature and fluid contraction. Deserves all the merit. Maritime environment as you say, is very agressive and there is never enough precautions in redundant sealing. Been a scuba diver for 30 years and experienced several unexpectations. Currently, am evaluating components sourcing to build the key buoyancy part of the contraption on two or three different schemes, test them as standalone (tether yes !) and much later to see housing in a PVC pipe fuselage. Something I must also consider is the delta T may not be enough at all locations the glider encounters while travels, as delta depths could be restrictive. So the contraption may work in open seas but to reach there from a 'shallow' waters launch will pose a challenge.

Thanks ! Contacting the private technology contractor should be a much better approach option. Will do.

In the name of science and technology, not warfare; what would be the correct way to find/approach a chief engineer involved with the military to propose improvements/modifications/changes to a current project ? Is anyone here in the forums working with the military forces, that could know or suggest proper contact paths ?

Because of the abundance of what you would call 'bad' foods. Any predator animal will eat first the most energy supplying parts of the killed victim, and leave the rest of the carcass for second thoughts -or next needs- if no other victims are found soon. The same predator, will go for broccoli to avoid starvation if nothing else is available. What you name 'good' foods can be a label pushed by nutritionists and not reality.

I do not think three dimensional works. Sound perceived from above and below cannot be achieved by synthesizing a psychoacustical illusion from only two speakers. Virtual surround illusion can be created by processing audio from only two channels, but that is not 3D, it is 2D Several companies have their own processing methods to the virtual surround.
